lMPROVEMENT lN |NVAL|DBE,DSTEADS.

Specification forming part of Letters Patent No. 36,578, dated September30, 1862.

To all whom it may concern:

Be it known that I, JOHN SEBO, of the city of Wilmington, county ofNewcastle, and State of Delaware, have invented new and usefulImprovements in Bedsteads; andl do'hereby declare that the following isa full and exact description thereof, reference being had to theaccompanying drawing, and to the letters of reference marked thereon,making a part. of this specification.

rlhe nature of my invention consists inthe shape Of the round andtapered rails D, to which the canvas is fastened, and in theirarrangement and combination with the adjustable rest E and movableroller J.

TO enable others skilled in the art to make and use my invention, l willproceed to describe its construction and operation, to wit:

-A represents the posts and rails that 'form the bedstead.

C is the canvas upon which the patient rests. A feather bed Or mattressis placed underneath this canvas upon the rails A. The canvas or stoutsheeting is tacked on and permanently Vfastened to round and taperedrails D, the

rails D being thicker in the center and tapering at both ends, so as tokeep the canvas 'tightly and evenly stretched in the center, where theweight of the patients body is the heaviest and tends to stretch and bagit. A square frame, E, upon which canvas is stretched and permanentlyfastened, serves as a rest for the body, which is adjusted, whenrequired, to any inclination Or horizontal position to suit the comfortof the patient by means of the iron rods G G, which extend downward onthe outside of the head of the bedstead, and tO which cords H H areattached at the lower ends of rods G and suspended from a revolvingrailor roller, J, operated by a crank, K. This rail J rests in the forksof two supports, L, attached tO head posts A, and has a ratchet, M, andthe crank K on one end. As the crank K is turned, the rail revolves andacts as a windlass, winding up the cords H H, and thus 'the square frameE is Y The aperture Q is for the patients use, andv underneath which avessel is placed, when required,without disturbing the patientby placingthe vessel between the canvas C and the bed or mattress. Between thefootposts A is a revolving rail, R, having a light wooden square frame,S, attached, to answer the purpose of a table or fan, by the cord T,attached to the adjustable pin U and spring V. Pulleys W,with a tighteningcord, X, ratchet Y,dog Z, and crank a, serve to revolve and holdthe rail D when lowering, raising, or stretching the oanvas C to thelevel required. The iron pins b, that are inserted through the posts Aand into the ends of rails D, fit into cast-iron plates d on the ends ofrails D, and can be withdrawn at any time and thrust through apertures ein the posts A, so as to allow the rails D, with the canvas C, to beraised afew inches higher when desirable.

The head-board f is a movable frame. It has extended legs that rest by atenon andmortise in the rail A, and when the patient requires to havehis head Or shoulders operated on Or wounds dressed the head-board f andcross-rail J can be instantly removed and again easily replaced. l

What I claim as my invention, and desire to secure by Letters Patent, is

The shape of the rails D and their arrangement and combination with thedevices E, G, and J, arrangedaud combined as described,

for the purposes set forth.

JOHN SEBO.
